Boggy pseudomass sonographic sign for testicular torsion

“Boggy” is a term that describes wet, spongy ground, typically with poor drainage (Fig. 1). In the scrotum, a “boggy pseudomass” (Fig. 2) is an indicator of testicular torsion [1, 2]. Recognized for decades now [3, 4] and first coined as a phrase in 2013 [2], this sign may be more frequently seen in testicular torsion than the better-known “whirlpool” sign of a twisted spermatic cord [1, 2]. A “boggy pseudomass” is an extratesticular, mass-like structure, consisting of redundant or enlarged spermatic cord extending down to epididymis, which itself can also become swollen and difficult to separate from the adjacent cord (Fig. 2) [2, 3].
